A first transistor can transfer a first voltage to a bit line. A stud bump is connected to the bond pad, and the stud bump and die are encapsulated with encapsulant. This plating solution is less toxic, not easily oxidized, and has a long life, thus offering great performance comparable with the cyanide-type gold plating solution. The physiologically ingestible composition of matter may be administered to reduce changes in blood oxygen saturation levels of a mammal undergoing stress.
